INDEPENDENT DVICE FOR KINTOSQOPES.

To all ahem it may concern: l

Be it known that l, JEAN A. Ln ROY, a citizen of the United States, and a resident of New York, in

the county of New York and State of New York, have l invented certain new and useful Improvements in Independent Framing Devices for 'Kinetoscopea of which the following is a specification. t 1

My-invention relates to kinetoscopes and it hasvfor its object to simplify the general arrangementand' construction of such apparatus and particularly to V`of said film with respect to the diaphragm in the said face .plate.

The nature of my invention will be best understood when described in connection with the accompanying Figure 1 is a rear view of the kinetoscope. Fig. 2 is a vertical section on the line 2 2 Fig. 1.. Fig. 3 is a view of theshutter and 'shutter actuating mechanism. Fig. 4 is a view of the shutter and face plate.

Figs. .5 and 6 are views of the entrance chute. `Fig. 7 is a plan view of a portion of the film.

Similar characters of, reference designate corresponding parts throughout the several views.

Referring now to the drawings, l() is the kinetoscope frame containing the mechanism for feeding and-conmening the' fum.

11 is the llens mount into whichth'e usual'projecting or taking lens may be mounted'. A The upper part of the frame 10 contains a continuous sprocket feed roller 12, a spring pressed roller 13 pressing against it, and la fixed guide roller 14. The' lower part contains a similar butintermittent sprocket roller 15 and spring pressed roller 16 acting thereon.

17 is a spring pressed gate of the usual construction inclosing the film 18 between it and the diaphragm 19 in the face plato 20. .lust below thisgate and frame is a fixed film guide rol1er-2 2.- Between the said gatey and the intermittent sprocket 12.1is a rack 23 and pinion 24. Fixed to this rack and moving 'with it is another roller.25 adapted'to adjust) the film 18 so as to frame vit with' respect to Lthe diaphragm 19 in the face-plate 20. The pinion 24 is connected with an operating thumb screw 26 outside the frame 10;

Motion to operate the continuous feed sprocket 12; intermittent sprocket 15 and shutter 21 is derived tltrough suitable gears from-the crank 27 .which is usually turned by hand. The continuous sprocket Speixication of Letters Patent. Application sied ramt 20,1908. serrure. 307.023.

eedand 'intermiQent sprocket and'v actuatingf'tnechanism for moving-the film between the gate arid. face plate isv old and well known.

21 is 'the shutter Whichis operated by means' hf the connecting rod 28 cccentrically attached to the intermittent wheel 29 or by equivalent means, andl comprisestwo pieces, 30 and 31 which are adapted to be broughttogether and separatedat the proper intervals. When the film is in rn'otion the shutter is closed,

vand is open when the film Vis stationary in the gate'.

I prefer to make these parts of the shutter of wire netting of about 36 mesh and thereby eliminate to a. great extent the disagreeable flicker prevalent .with the usual opaque shutter. I may of course use in place of the shutter shown the rotating shutter common to' devices of this character.

The film 18 is taken from a suitable reel or box and passes through the entrance chute 32 which consistsA rat of a funnel shaped body 33 carrying two fixed protecting rollers 34 and 35, said body 33 being pivotally attached to swing within the. housing 36 adapted to be fastened to the top of the frame 10. The film after 'passing through this entrance chute 32 which will .choke any rire land prevent ignition of the entire film,

passes aroundthe fixed guide roller 14,v and then between the sprocket feed roller 12 and the spring pressed roller'lS. A loop 37 is then made in the film before it reaches the gate 17. It then passes between the said gate and the face plate past the diaphragm 19. dipen leaving the gate 17 it passes-about' the fixed guide It' then leaves the mechanism through an exit chute.. 38 'com rising a flat narrow metallic chute which 'willlikewise choke any fire and prevent burning of the entire 51m. This chute empties into a suitablemag` zine or receptacle 39 which is made fire-proof and is adapted: to contain-the loose film until it is desired to rewind the same upon a reel.

. Theoperation of theadjustable roller 25 to frame the picture of the film with respect to the diaphragml 19 in the face plate 20 is as follows. By turning the i.

thumb screw 26 the attached pinion 24 moves the rack 23 accordingly, and thereby the roller 25, the Vextreme positions of which are indicated in Fig. 2. Thel roller in thus moving permitsof the shortening or lengthen.-

ing of the loop 37 thus adjusting 'o r framing thepiture .with respect to said diaphragm 20 as may be desired..

While I haveshown the roller'actluated. by a rack Land pinion I do not wish to restrict myself to this par- `ticular means as it'is evident that equivalent means such as a cam or screw may be used to impart movement to the roller. Neither do I wish to rest'n'etmyself to any particular form or shape of the roller itself` l es' l may substitute for the roller shown, e. sprocket roller thereby preventing the surface of the lin from .rubbing on the miler.

Ai en; aware that means are knpvzn to register or freine the picture of e. lm, but. these means require the entire iln feeding mechanism or the face plete end iene ino-be moved to accomplish this end, Whereas my menne ero independent oi the reet of the rneclifin- .ieniend acts through tlie'sliortening oi' lengthening 0f the ioep 37 by the backward or iorwerd motion o the if 25. v

y tne Word independent l Wish to be understood es inea-ning no1/dependent upon the moving or changing of poition of any 'part or parts of the iin feeding mechenem, or the ece plateend lens.
